Peugeot 308 1.2 PureTech engine problems: buyer checks
Peugeot 308 1.2 PureTech engine problems on the T9 and new 308: belt, oil pump and turbo checks plus resale value effects.
· 7 min read
Peugeot 308 1.2 PureTech engine problems affect the second-generation 308 (T9, 2013–2021) and belt-engined cars of the third generation from 2021. The oil-immersed timing belt can shed debris that blocks the oil pump strainer and starves the turbo and brake vacuum pump of oil. Check service records, inspect the belt and read the fault memory before buying; price cars without belt evidence lower.
Which 308 generations use the 1.2 PureTech?
The 1.2 PureTech is the main petrol engine in the 308 from 2013 onwards. The first-generation 308 (2007–2013) used different engines and is not part of the PureTech story.
| Generation | Years | Bodies | 1.2 PureTech versions | Other petrol options |
|---|---|---|---|---|
| 308 II (T9) | 2013–2021 | Hatchback, SW estate | 110 and 130 PS turbo (some markets also lower outputs) | 1.6 THP in GT and GTi |
| 308 III (P5) | 2021– | Hatchback, SW estate | 110 and 130 PS turbo (belt) | Plug-in hybrids; Hybrid 136 with chain from 2023–2024 |
The warranty extension Stellantis introduced in March 2024 covers 1.2 turbo engines built from April 2014 to June 2022, so most T9 cars and early third-generation cars fall inside it. Later belt engines are not named in that list but share the same design, so check them just as carefully.
Peugeot 308 1.2 PureTech engine problems: symptoms of a failing belt
A failing PureTech belt rarely gives a clear early warning; most symptoms appear only once debris has started to block the oil system. That is why checks on a stationary car matter as much as the test drive.
Warning signs to look and listen for:
- Oil pressure warning light, often at hot idle or after a motorway run.
- "Engine fault" or "Braking assistance fault" messages, or a hard brake pedal, caused by the oil-fed vacuum pump losing supply.
- Black particles on the dipstick, under the oil filler cap or in drained oil.
- Camshaft timing and oil pressure fault codes in the engine control unit.
- Loss of power or limp mode, sometimes with a rattle from the timing area.
- Turbo noise or smoke, because the turbo's oil feed can also be restricted by debris.
If you find any of these on a car you are about to buy, assume a belt replacement plus oil system cleaning at minimum, and possibly a turbo or engine.

MyCarDealer compares any car from an auction or listing with the market in your country and shows the net margin after VAT, transport and costs – and the maximum bid.
Request accessBelt, oil pump and turbo checks for dealers
The checks below cover the parts that fail in a typical PureTech damage chain: belt, oil pump strainer, turbo and vacuum pump. A workshop can do them in about an hour.
- Service records: oil changes at the specified interval and oil grade, belt inspections at services, and any belt replacement invoice.
- Belt inspection: visual check through the oil filler and measurement with the manufacturer's gauge; a swollen belt must be replaced.
- Oil condition and level: particles, sludge and top-ups between services.
- Oil pressure: a mechanical gauge reading if the warning light has ever come on.
- Fault memory: engine, brake booster and turbo-related codes.
- Turbo: shaft play, oil in the intake, smoke on acceleration.
- Brake vacuum: pedal feel after several stops with the engine idling.
| Finding | Likely work | Bid approach |
|---|---|---|
| Recent documented belt replacement, clean oil | None | Bid close to market |
| Full history, belt never changed, gauge OK | Plan belt at due interval | Small deduction |
| Gaps in history, belt not inspected | Belt job and inspection | Deduct a full belt job |
| Particles in oil or oil pressure faults | Belt, strainer, oil system cleaning, maybe turbo | Bid very low or pass |

Is the 308 SW PureTech worth buying for stock?
Yes, a 308 SW PureTech is worth stocking if it has full history and a documented belt check, because estates sell well to families and fleets and the PureTech SW is cheap to buy. Without that evidence it is a price-led car with real comeback risk.
According to listings tracked by MyCarDealer in eleven European countries in October 2026, 2017–2020 308 SW estates with the 1.2 PureTech had a median asking price of €7,984 across 171 listings (median 120,000 km), almost the same as the hatchback. Buyers do not pay an estate premium on this model, so your margin has to come from buying correctly.
The SW suits buyers who want space for little money and drive mostly short and medium distances. Long-distance drivers, especially in markets such as Italy where the 308 diesel is popular, often prefer the BlueHDi.
How much value does PureTech risk remove?
The PureTech risk shows up as a discount against diesel 308s of the same age, which in our data is clear even though the petrols have lower mileage.
| 308 version | Years | Listings | Median price | Median mileage |
|---|---|---|---|---|
| 1.2 PureTech (all bodies) | 2017–2020 | 334 | €7,999 | 110,000 km |
| Diesel (BlueHDi) | 2017–2020 | 628 | €8,799 | 138,000 km |
| 1.2 PureTech, third generation | 2022–2023 | 381 | €16,500 | 63,000 km |
The 2017–2020 petrol was asking about €800 less than the diesel, despite 28,000 km less. Normally the lower-mileage car would be the dearer one, so the real PureTech discount is larger than the headline gap. Diesel demand varies by country, as our article on used diesel demand explains, but the direction of this comparison is consistent across markets.
Pricing the 308 PureTech before bidding
Price a 308 PureTech in two steps: first against other 308s of the same generation, body and engine, then adjust for the belt evidence. The first step gives you the market; the second gives you your real cost.
- Documented belt replacement: value at market; mention it in the advert.
- History complete, belt never replaced: deduct part of a belt job and tell the buyer what is due.
- Unknown history: deduct the full cost of a belt job and oil system cleaning, which French workshop guides put at roughly €800–1,200 for the belt alone and up to €1,500–2,500 with the oil pump and related parts.
Check whether the car is still within the 10-year or 175,000 km extended cover and whether the maintenance conditions are met; it can turn a risky car into an attractive one.

Frequently asked questions
Which 308 generations use the 1.2 PureTech?
The second-generation 308 (T9, 2013–2021) and the third generation from 2021 use the belt-driven 1.2 PureTech. Hybrid versions introduced from 2023 use a chain-driven engine, and the first-generation 308 used different engines.
What symptoms show a failing PureTech belt?
Common signs are an oil pressure warning, braking assistance faults or a hard brake pedal, black particles in the oil, camshaft timing fault codes and loss of power. Many cars show no symptoms until debris has already blocked the oil pump strainer.
Is the 308 SW PureTech worth buying for stock?
Yes, if it has full service history and a documented belt check or replacement. In our October 2026 data, 2017–2020 SW PureTechs asked a median of €7,984, so profit depends on buying them cheaply.
How much value does PureTech risk remove from a 308?
In our data, 2017–2020 308 PureTechs asked about €800 less than diesels of the same years despite lower mileage. For a single car without belt records, deduct the cost of a belt job from your bid.
Does the PureTech warranty extension cover the 308?
Yes. The 308's 1.2 turbo engines built from April 2014 to June 2022 are covered for up to 10 years or 175,000 km for belt-related oil pressure faults, provided the car was serviced to schedule.
